Not gonna lie, the shaker is very durable so I’m not sure what people are saying about the cap breaking cos I use mine everyday and it’s still in perfect structural condition! The only downside is that it does start to smell a bit off and I’m unsure how to get rid of the smell. Other than that, it keeps my protein cooler for longer and feels mad boujee

I don’t usual carry it around, so can’t speak about endurance of the item. But it is just what I wanted to have in my home to have my shakes before and after gym, no smells in this bad boy, contrary to all the plastic shakers. Is just a bit too big, so no great to carry around in my opinion.

Awesome shaker, holds the liquid in it.

Shaker is leak proof and does exactly what you expect love this product 

I've had 2 bottle lids fail in exactly the same way. The way the lid is meant to be lifted causes the tab protruding to tear away from the stopper part. Disappointing as the metal shakers are much easier to clean than the plastic ones
